Abstract

The invention provides an automatic reclosing driving device of a miniature circuit breaker. The automatic reclosing driving device is characterized in that the device is formed by a plastic casing, a 42TYZ / CW / CCW type permanent magnet synchronous motor, a crank, a shaft pin, a micro switch, and an electronic circuit board, the automatic reclosing driving device and the miniature circuit breaker are mutually matched and assembled together, the automatic reclosing function of the miniature circuit breaker is realized, the closing of the miniature circuit breaker can be remotely and automatically controlled, and the automation need of a low voltage power distribution system is satisfied.

Description

1. Technical field [0001] The invention relates to an automatic reclosing device for a small circuit breaker or a miniature circuit breaker in the low-voltage electrical field, in particular to an automatic reclosing drive device for a miniature circuit breaker. 2. Background technology [0002] At present, most of the multi-functional miniature circuit breakers or multi-functional miniature circuit breakers in the domestic low-voltage electrical appliance market only have manual closing or opening and automatic disconnection for abnormal protection, but do not have automatic reclosing that can meet the automation requirements of low-voltage power distribution systems. Brake function, develop an automatic reclosing drive device matched with the miniature circuit breaker, realize the automatic reclosing function of the miniature circuit breaker, and meet the automation requirements of the low-voltage power distribution system. 3. Contents of the invention [0003] The purpo...
